Generally speaking, the red K first represents the positive column, and the green K line has the negative column. (Note that there are also some disks with red columns and green columns. The color can be adjusted according to personal preference. ) A positive column indicates that the price rises over a period of time, and a negative column indicates that the price falls over a period of time, which can be 1 minute, 5 minutes, a week or a month.
